-Ever needed to **how to extract metadata** from documents programmatically in your Java applications? Whether you're building a document management system, implementing file validation, or creating automated workflows, pulling file size, page count, and format information can save you countless hours of development effort. In this guide we’ll walk through everything you need to know to retrieve document metadata efficiently with GroupDocs.Comparison for Java.
+If you’re building a Java‑based document management system, you’ll quickly discover that pulling **metadata**—such as file size, page count, and format—is essential for validation, indexing, and user‑friendly displays. In this tutorial we’ll show you how **groupdocs comparison java** makes metadata extraction simple, reliable, and performant. By the end, you’ll be able to query document properties with just a few lines of code and integrate the results into any enterprise workflow.
 
 ## Quick Answers

-## How to Get File Size in Java
+## How to Get File Size in Java (java get document size)
 GroupDocs.Comparison exposes the file size through the `DocumentInfo` object. After loading a document, call `getSize()` to retrieve the size in bytes, then convert to KB/MB as needed.
 
-## How to Get Page Count in Java
+## How to Get Page Count in Java (java get page count)
 Similarly, `DocumentInfo.getPageCount()` returns the number of pages. This is useful for pagination, progress tracking, or estimating processing time.
 
-## How to Determine File Format in Java
+## How to Determine File Format in Java (java determine file format)
 Use `DocumentInfo.getFileType()` to obtain the detected format (e.g., PDF, DOCX). This helps you enforce format‑specific logic or display friendly names to users.
